2. gLite and INT.EU.GRID training for end-users
Outline
In order to query directly the IS two high level tools are provided:
lcg-infosites
lcg-info
These tools should be OK for common user needs
These tools hide the complexity of raw LDAP queries (ldapsearch)

lcg-infosites
The lcg-infosites command
used to obtain VO-specific information on Grid resources
lcg-infosites --vo <vo> <option> -v <verbosity> -f <site> --is <bdii>
--vo <vo>: the name of the VO to which the information to print is related (mandatory);
<option>: specifies what information has to be printed. It can take the following values: ce, se, all, closeSE, tag, lfc, lfcLocal, rb, dli, dliLocal, vobox, fts
--is <bdii>: the BDII to query. If not specified, the BDII defined in the environment variable LCG_GFAL_INFOSYS will be queried.
-f <site>: restricts the information printed to the specified site (it applies only to options rb, dli, vobox and fts).

lcg-info
Query the BDII, in a deeper way, the BDII
It requires to set LCG_GFAL_INFOSYS to the value of the BDII to be used:
export LCG_GFAL_INFOSYS=i2g-ii01.lip.pt:2170
Prints the list of the CE's, SE's, services or sites satisfying a given query

lcg-info: Usage
lcg-info --list-ce [--bdii bdii] [--vo vo] [--sed] [--debug] [--query query] [--attrs list]
--list-se
--list-service
--list-site
lcg-info -list-attrs
lcg-info -help
The query syntax is the following:
attr1 op1 value1, ... , attrN opN valueN
where attrN is an attribute name, op is =, >= or <=, and the cuts are AND'ed. The cuts are comma-separated and spaces are not allowed.

ldapsearch
The LDAP servers can be queried directly with the ldapsearch command.
For the LDAP implementation of the GLUE schema, the root of the Directory Information Tree (DIT) is always: o=grid.
At the GRIS level the next entry is either:
mds-vo-name=local (for globus-mds service port 2135).
mds-vo-name=resource (for BDII service port 2170).
At the GIIS (site) level:
mds-vo-name=<SITE NAME> (BDII service port 2170)‏
At top level:
mds-vo-name=local (BDII service port 2170)‏
